SHEET-METAL BOAT.

To all whom 'it may concern:

B e it known that I, GEORGE H. HYDE, of Watertown, in the county of Jefferson, State of New York, have invented new and useful Im rovementsin Sheet- Metal Boats, of

'Whlch the following, taken in connection with the accompanylngdrawings, 1s a full,

clear, and exact description.

This invention relates to certain improvements in the manufacture ofsheet metal motor' boats, row boats and similar small v(water craft, andrefers more particularlyl to the construction of the blanks which formthe shell to ive such shell the desired form,-

rigidityan s'nunetry with the least pos,-

expense. The main object is to enable the blanks, which are to formtheshell, to be manufactured and sold to boat builders and others inflat, knocked-down condition and readilyl r1veted orl otherwise securedtogether at.

their meeting edges without further cutting lor fitting, so that theassembled parts will Yassume the desired form, rigidity and sym- 'metryready to launch and recive such other trimmings or 'fittings as may bedesired. In other words, I have sought to produce a shell exclusively ofthe keel and sometimes the stern piece from duplicate sets of flatpieces of sheet metal of suitable gage, each piece extending from bow tostern, and previously cut in such manner that when their meeting edgesare secured together, the

shell will assume the desired form.

following description: In the drawings-Figures 1, 2 and 3 arerespectively a top plan, a side elevation and .longitudinal -verticalsectional view of a motorboat embodying-the various features of myinvention. Fig. 4 is `an end view show-v ing the lines upon which theshell is de-l ve oped.v Figs. 5, 6, 7,8 and 9 are transverse sectionalviews taken respectively on lines 5 5, 6 6, 7 7, 8 8 and 9 9, Fig. 2.Figs. 10 and 11 are enlarged sectional views taken respectively on lines10 10 and 11- l1, Fig. 2. Figs. 12 and 13 areplan viewsv of the detachedsheet metal blanks for form'- `ing one'half of the shell. Fig. 14 is aplan view of the blank keel piece. Fig. 15 is a plan top plan of theblank for forming the deck or top of the boat. Fig. 17 is a plan view ofSpecification of Letters Patent. Application led February 13, 1909.Serial No. 477,701.

one of the detached bulkheads. Fig. 18 is an elevation of the bow beam.

The shell of the boat is' composed of duy plicate sets of sheet metalblanks 1 and 2 ,those of one set forming one side of .the boat and thoseof the other set forming the opposite side ofthe boat, althouvh in thisinstance I employ a sheet meta keel piece 3 and vsheet metal stern pieceLl- The stern piece lt may, however, be omitted and the correspondingends of the op osite sets of side and bottom pieces 1 an 2 are secureddirectly to each other.

The blanks shown in "Figs, 12 and 13 form the side and bottom of onehalt' of the shell, it being understood that ar corresponding set ofblanks are employed to form the opposite side of the shell, and,therefore, whatever may be said of the blanks of one set applies alsotothe blanks of the of one side of. the boat withthe exception of thekeel piece 3 which"` is very narrow and is simply used as a convenienttie piece between the meeting keep edges of the blanks 2 and also forreceiving and sustaining an auxiliary keel 5 of wood, which serves as abufer to protect the metal from undue wear in drawing the boat into landout of the water. The transverse width of the plate 1 diminishesprogressively from the ends toward the center, sothat the ends areslightly wider than the intervening portions, and are deflected upwardlyat a slight angle to give the proper pitch to the bow and stern of theboat, the lower vedge of said blank 1 being nearly or substantiallystraight.- T he blank 2 which constitutes substantlallv one half of oat,pro essthe ends toward the center, the upper edge being graduallyconvexed from end to end and is of substantially the same length as thelower ed e of the blank 1 to which it is adapte to be secured'byvsuitable fastening means, as rivets 6 it being understood that themeeting edges of the plates 1 and 2 will lap one upon the other, and areprovided with 'registering rivet holes to receive the rivets. The frontedges of the blanks 1 and 2 are curved upwardly and forwardly inco-i'ncident curved lilies to give the desired form to the bow of theboat, while the rear ends of the saine elements are also inclined togive the desired form to the stern of the boat, and in this particularinstance are inclined downwardly and rearwardly and are attached byrivets or other simple fastening means to the side and bottom edges ofthe stern piece -4-- The front ends of the sheet metal blanks -1- and 2are secured to the opposite faces of a similarly curved bow beam --7-,preferably made of steel and extending from the upper point of the bowdownwardly a short distance to the rear `of said bow, where it forms apart of the keel. The sheet. metal keel piece 3 extends from the rearend of the bow beam 7- to the stern ol' the boat, and its oppositelongitndinal edges are deflected upwardly and laterally to lit closelyagainst the inner faces of the adjacent edges of the lower sheet metalblanks -2-, and are secured in place by suitable rivets -8-, therebyforming a watertight connection Vbetween the 'lower keeledges of theside pieces -2-. A sheet metal finishing shield or casing -9- is titledaround the front and side edges of the plates 1 and -2- and interposedbow beam -7-, and is held in place by rivets ,sheet metal plates formingthe sides and ,-10 g passing transversely through the adjacent parts,said shield extending some distance rearwardly beyond the rear end ofthe bow piece -7- for receiving and inclosing the front end of anauxiliary keel piece- -5-, which latter is coincident in length with thesheet metal keel piece v3- to protect the latter from undue wear-oinjury in drawing the boat into and out of the water.

'ln Figs. `--12--, -13- and also in Fig. --l I have shown a series ofcordinate lines or loci lettered alphabetically from a to n inclusive,so that by comparison of the lines in diagrammatic view shown in Fig. 4,certain positions on the blanks may be readily located in thediagrammatic View of the boat. Y

In Fig.- 3 I have shown two bulkheads -14- and -15-- locatedlrespectively near the bow and stern of the boat, forming, to; getherwith the top section, as --l6, air

tight compartments 1S-- andl -19- to being secured in a suitable mannerto the v inner faces of the side pieces or blanks -`2-.

The main feature of my invention, however, consists in the construct-ionof the flat sheet metal blanks -land -2-v, which, in ordinary row boatconstruction, may form the entire boat, using the sheet metal keelpiece.-3- when necessary.

`What l claim is j 'In a sheet metal boat duplicate sets of bottom ofthe boat, those of each set being disposed one above the other, theupper section gradually diminishing in width from its ends toward thecenter, and a lower sec-` tion gradually increasing in width from itsends toward the center, the adjacent lengthwise edges of the plates ofeach set being of substantially the same length. .Y

In witness whereof l have hereunto set my hand this 9th day of February1909.

GEORGE HYDE.
